Dear Mohttat ,
in Ericsson Technology ICMBAND is messuring the uplink interference and how to measure the uplink interference on the ground is not possible wiht the DT Tool , only by the spectrum analyzer . As experienced the external interference is in 2 type, DL & UL .
DL interference is causing by the BCCH either home Network or other Operators and UL interference is causing by Jammers .
Action Point :
For the DL interfernce change the BCCH for the home NW or neighbor operators .
For UL interference , conslut wiht the ATRA to support you for stopping the Jammers source or shift your freqquency type from 900 to 1800 or from 1800 to 900 whatever is pinging you .
